First of all, there are many binary stars who have the 2nd (or even 3rd)
member of the group at a distance far greater than Jupiter and the Sun. As
it is, Jupiter is two small to form a true star, it's even to small for a
brown dwarft. But kooks like those others paid no heed to what sci-fact
tells us and just go on ratlltling their empty heads around on the
newsgroups.

Our Sun, a Main Seq. G Class star is a SINGLE star with no other stellar
objects in orbit with or around it, all it has are planetary and smaller
objects.

"Evidence Mounts For Sun's Companion Star"

"The Binary Research Institute (BRI) has found that orbital
characteristics of the recently discovered planetoid, "Sedna",
demonstrate the possibility that our sun might be part of a binary star
system. A binary star system consists of two stars gravitationally
bound orbiting a common center of mass. Once thought to be highly
unusual, such systems are now considered to be common in the Milky Way
galaxy."

"Because eccentricity would likely fade with time, it is logical to
assume Sedna is telling us something about current, albeit unexpected
solar system forces, most probably a companion star".

"But with Dr. Brown's recent discoveries of Sedna and Xena, (now
confirmed to be larger than Pluto), and timing observations like
Cruttenden's, the search for a companion star may be gaining momentum."
